What is the voltage of the 0.25-C charge in Exercise 7?
Exercise 7
A current of 1.50 A flows in a conductor for 6.0 s. How much charge passes a given point in the conductor during this time? To separate a 0.25-C charge from another charge, 30 J of work is done. What is the electric potential energy of the charge?
